Answer:
1
Step-by-step explanation:
cos²θ (1 + tan²θ)
Use Pythagorean identity:
cos²θ (sec²θ)
Its 13, because you multiply -8 and the negative beside it which turns it into a positive so you add 8 and 5
The value of is
We want to evaluate .
The base of this logarithm is and the number is .
We need to express the number as the base raised to a certain index.
This implies that,
Recall now that,
.
We apply this property to obtain,
Recall again that,
.This implies that,
The correct answer is C.
1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289
The pattern will lead to the answer being all the perfect squares from 1 to 300.
